Abstract

We report the demonstration of mechanically flexible quantum dot light emitting diodes (QD-LEDs) of all three primary colors (red, green, and blue). The QD-LEDs have been fabricated over poly(ethylene-terephthalate) substrates and exhibited high brightness, saturated colors, and pronounced flexibility with a critical bending radius of ∼5 mm. The efficiencies of the flexible QD-LEDs are comparable with the devices fabricated on rigid substrates, suggesting the intrinsic flexibility of quantum dot-based optoelectronic devices.
